A new organelle called a hemifusome has been discovered in human cells. The hemifusome is a small structure that is around 100 nanometers in diameter and has a shape like a snowman wearing a scarf. It was discovered using a method called cryo-electron tomography, which involves rapidly freezing cells to preserve their structures. The hemifusome may be involved in sorting, recycling, and discarding proteins within human cells. Further studies are needed to determine the exact role and function of the hemifusome.
